Red Tacton

Red Tacton

                        There is new concept of “RED TACTON” which makes the humanbody as a communication network by name HAN (Human Area Network).RedTacton is a  new innovative Human Area networking technology that turns the surface of the humanbody as a safe, high speed network  transmission path. It is completely distinct from wireless and infrared technologies as it uses the minute electric field emitted on the surface of the humanbody. NTT lab from Japan is currently testing & developing this revolutionary technology. Red Tacton is the major requirement and advantage

for people. Using RedTacton, communication starts when terminals carried by

the user or embedded in devices are linked in various combinations according to the user's natural, physical movements.  Communication is possible using any body surfaces, such as the hands, fingers, arms, feet, face, legs or toes. RedTacton works through shoes and clothing as well. A transmission path is formed at the moment a part of the human body comes in contact with a RedTacton transceiver, physically separating ends the contact and thus ends communication. The chips which will be embedded in various devices contain transmitter and receiver built to send and accept data in digital format.                       

                         In an attempt to increase the understanding of red tacton, we have to understand the “What exactly is red tacton? How does it work? what are the different applications? and future development of red tacton " etc are discussed.

 

 I. Introduction

Red Tacton is a new Human Area Networking technology that uses the surface of the human body as a safe, high speed network transmission path. It is completely distinct from wireless and

infrared technologies as it uses the minute electric field emitted on the surface of the human body. A transmission path is formed at the moment a part of the human body comes in contact with a Red Tacton transceiver.  Communication is possible using any body surfaces, such as the hands, fingers, arms, feet, face, legs or torso. Red Tacton works through shoes and clothing as well. When the physical contact gets separated, the communication is ended[1] .

Using Red Tacton enabled devices, music from a digital audio player in your pocket would pass through your clothing and shoot over your body to headphones in your ears. Instead of fiddling

around with a cable to connect your digital camera to your computer, you could transfer pictures just by touching the PC while the camera is around your neck. And since data can pass from one body to another, you could also exchange electronic business cards by shaking hands, trade music files by dancing cheek to cheek, or swap phone numbers just by kissing.

Touch and action gives Tacton, and word Red – a warm colour – to emphasize warm and cordial communications. This technology was developed by Japanese Company Nippon Telegraph and Telephone Corporation. Fig 1: red tacton

II. How Red Tacton works?

Using a new super-sensitive photonic electric field sensor, Red Tacton can achieve duplex communication over the human body at a maximum speed of 10 mbps. The Red Tacton transmitter induces a weak electric field on the surface of the body. The Red Tacton receiver senses changes in the weak electric

field on the surface of the body caused by the transmitter [2].

Red Tacton relies upon the principle that the optical properties of an electro-optic crystal can vary according to the changes of a weak electric field. Red Tacton detects changes in the optical properties of an electro-optic crystal using a laser and converts the result to an electrical signal in an optical receiver

circuit. The transmitter sends data by inducing fluctuations in the minute electric field on the surface of the human body. Data is received using a photonic electric field sensor that combines an electro-optic crystal and a laser light to detect fluctuations in the minute electricfield.

III. Transmission Steps [3]

1. The Red Tacton transmitter induces a weak electric field on the surface of the body.

2. The Red Tacton receiver senses changes in the weak electric field on the surface of the body caused by the transmitter.

3. It relies on the principle that the optical properties of the electro-optic crystal varies according to the changes in the weak electric field.

4. It detects the changes in the optical properties of an electro optic crystal using a laser beam and converts the result into an electrical signal in a detector circuit.

IV. Red Tacton Transceiver

The block diagram of a Red Tacton Transceiver [4]. The signal from the interface is sent to the data sense circuit and the transmitter circuit. The data sense circuit senses the signal and if the data is present it sends control signal to the transmitter which activates the transmitter circuit. The transmitter circuit varies the electric

field on the surface of our body. This change in the electric field is detected by the electro-optic sensor. The output of the electro optic sensor is given to the detector circuit, which in turn given

to the interface of the receiving red tacton device.

V. .MECHANISM  OF  RED TACTON

Data is received using a photonic electric field sensor that combines an electro-optic crystal and a laser light to detect fluctuations in the minute electric field. The naturally

occurring electric field induced on the surface of the human body dissipates into the earth. Therefore, this electric field is exceptionally faint and unstable. The photonic electric field sensor developed by NTT enables weak electric fields to be measured by detecting changes in the optical properties of an electro-optic crystal with a laser beam.

Figure shows the various electric fields on the surface of our body induced by the RED TACTON device. Only a portion of the induced electric field is sensed by the receiving REDTACTON device. The remaining electric fields are dissipated to the ground.

VI. Applications of Red Tacton

There are many applications of red tacton in different fields. This technology will widely used in daily working schedule and provide

convenience to people [5].

A. One–To–One Services

1. An Alarm

Red Tacton devices embedded medicine bottles transmit information on the medicines attributes. If the user touches the wrong medicine, an alarm will trigger on the terminal he is carrying.

The alarm sounds only if the user actually touches the medicine bottle, reducing false alarms common with passive wireless ID

tags, which can trigger simply by proximity as shown in fig. 4.

Fig. 4: One-To-One Services

Fig. 4 shows an alarm sounds automatically to avoid accidental medicine ingestion in the first application on the left side of fig. Right part of fig. 4 describes touch advertising and receive Information.

2. Touch Advertising

When a consumer stands in front of an advertising panel and information matching his or her attributes is automatically displayed. By touching or standing in front of items, consumers can get more in-depth information.

B. Intuitive Operation

1. Touch a printer to print

Print out where you want just by touching the desired printer with one hand and a PC or digital camera with the other hand to make the link Complicated configurations are reduced by downloading device drivers “at first touch” as you see in fig. 5.

2. Instant private data exchange

By shaking hands, personal profile data can be exchanged between mobile terminals on the users. (Electronic exchange of business

cards) Communication can be kept private using authentication and encryption technologies.

C. Personalization

There are many applications under personalization. Some applications are shown in fig. 6.

1. Just Touching a phone makes it your own

Your own phone number is allocated and billing commences .Automatic importing of personal address book and call history. 

Fig. 6: Personalisation

2. Personalisation of Automobiles

The seat position and steering wheel height adjust to match the driver just by sitting in the car [6]. The driver’s home is set as the destination in the car navigation system. The stereo plays the driver’s favorite song.

3. Wireless Headset

Red Tacton can carry music or video between headsets, mobile devices, mobile phones, etc. Users can listen to music from a Red Tacton player simply by putting on a headset or holding a viewer.

4. Conference System

An electrically conductive sheet is embedded in the table. A network connection is initiated simply by placing a lap-top on the table. Using different sheet patterns enables segmentation of the table into subnets.

D. Security Applications

Red Tacton is very secure in all respects such as authenticity, authorization and verification as well as unlocking as we see in fig. 7.

1. User verification and unlocking with just a touch

Carrying a mobile Red Tacton capable device in one’s pocket, ID is verified and the door unlocked when the user holds the doorknob normally. Secure lock administration is possible by combining personal verification tools such as fingerprint ID or other biometric in the mobile terminal.Fig.7:SecurityApplication

2. Automatic access log:

There is also a facility to access automatic log for confidential document storage. These access logs contain database information in the form of log files.

E. Other Applications

1. Under Water Communication

Red Tacton allows communication in outer space and in water where the speech constraints are very high and thus enables a highly efficient means of expression of speech which is beyond the purvey of human beings.

2. Communication inside body

Red Tacton is also used for the treatment. In human body, it is used to detect ailments such as abnormal growths, tumors and excrescences affected tissues and thus helps in curing different

diseases.

VII. CONCLUSIONS

 The need for artificial body implants to communicate with each other as well as to report back to a portable device could have quite some value. In fact, according to other researchers, the most important application for body-based networking may well be for these type of communications within, rather than on the surface of, or outside, the body. Redtacton technology is expected to dominate Bluetooth technology in the future. Red tacton technology could put the use of cables to an end. The problem faced by the Red tacton technology is the cost of development. This technology brings a new dimension of communication which effectively links the user to anyone he wants to communicate. Since it provides high speed communication, it can provide seamless service wherever, whenever and whoever uses it.
